SHINGLE STE/I? AND BEETHOD OF MAKING- 1'1.

Application filed September 17, 1920. serial Flo. 410,841.

To all whom it may concern:

Be it known that l, DoNALn'A. CUMrnn, a citizen of the United States, residin at Detroit, in the county of Wayne and state of Michigan, have invented certain new and useful Improvements in Shingle Strips and Methods of Makin Them, of which the foL lowing is a specification.

The invention relates to improvements in shingle strips and a method of making them.

The objects of the invention are to improve the appearance, decrease the costof construction and make or more durable and efic-ient shingle simulating strip.

l he invention is especially concerned w1th asphalt roofing into Which a paper .or felt base may have en. overlying layer of aspholt deposited thereon with an outer coating of slate or other mineral substance adhering to the asphalt to give it color, cherecteristic of the minernl coating. Roofing of this general character is inade in long continuous sheets end thereafter notched out into strips which, when properly leid on the roof present the eppeerence of separated shingles. Eech strip is notched transversely, at intervals, to give the eppearonce of seporoted shingles, at the notched ends. When the strips ere laid upon r. roof the notches of one course ere pieced midway between thenotches oi the adjacent courses and thus .onl the ports of the strips between the boon ing notches are visible to the eye of the observer.

The separated tebs, of such strips, are more liable to be liftedby wind end rain then would be the case if the strips were not divided into n plurality of tobs or shingle adhering parts or if the notches did not extend entirely thru the strip structure. Except for eppeerences the strip would moire a better root if they were not so trensversely notched.

carrying my invention into efiect, l depress selected areas of the mineral into end below the asphalt layer which overlies the sheet of felt so that in those selected areas the color or the asphalt shows eleerly thru the slate or other finely divided minerel matter, the slate being thus submerged in the asphalt, the block color'will show in contrast to the overlying costing ot mineral, end the black color thus reduced being about as wide and long as t e ueuel slot -mede in the shingle strip, will hove the eppeerence of complete seporotion es the usual s iparate shingles, when laid upon the roof. lls produces a very superior article because the strip remains in e. single piece unslotted, thereby being stronger and less liable to curl up by thc-efi'ect of the sun or by the effect of wind and storm when placed upon the roof.

In Figs. 1 and 3 of the drawings l have shown a schematic arrangement of apparatus by which the invention may be carried intoellect.

Figs. 2 and 4 show themanner in which the sheet may be divided into a plurality of strips. In Fig. 2 the strips are out from the sheet lengthwise of the strips and the sheet is divided longitudinally into a nurn ber of long strips, from which the shingle strips are severed. ln Fig. l the strips are cut the length of the shingle in width and transversely of the sheet.

Fig. 5 is a section of the stripsthrn lines 5-5 of Fig. l and thru lines 5-'-5 of Fig. 2, showing the depressed area or irerfs.

The sheet of roofing materiel 10, made in the mennerheretoiore described, passes over the folder or telre up ll, as usual. It then takes e path between the rollers 12 end 13 and under s roller l l end finelly over the roller 15. it then passes between the rollers 16 and 17, the former having four depress ing extensions 18 extending radially from the circumferential suri ece o1? the roller 16. The distance that the extensions 18 ere apart is substantially equel to the distances between two 'adjecent depressed cross or kerts l9 mode in the shingle simulating strip 20. 21 is the sheet of felt forming thebase for the sheet of roofing materiel and 22 is the overlying leyer of espholt. 23 is 93 the overlying covering of nnulor, or otherwise divided mineral, suc es slate and the like, which gives color to the rooiin stri s.

24: and 25 ore slitting lonives which s it the sheet on the line 25 of Fig. 2, while the m rotating guillotine lmiife 26 cuts the sheet showjii in l i 2, transversely on the line 27. The rol ers 28 end 29 represent the con'ventionel feed rollers by which the strip is drown thru the machine. Looking et, Fig. 5 it will be noticed that the depressions 19 are made below the surtoce 23 end into the surface 22. When the. slate is pressed down into the body of the ospholt layer 22,

the esphalt will rise up and completely cover 31% the area of slete to which the ressure is epplied, therefore mehing the her 19 black,

or the color of the asphalt, which when viewed, after the strips have been placed upon the roof, will look as much like a separation between adjacent tabs of the strips as if the strips were notched or cut throu usual. The pro'ections 18 extend in a irection parallel wit the axis of the roll 16 while the projections 18' of Fig. 3'extend circum. ferentially of the roll 16. That is because the strip 10 is'divided somewhat differently in the two examples. The rolls 16-16 may be either cold or hot but usually better results are produced when. the rolls are hot,

'especially is this true when the strip 10 in Fig. ,mentof the knife being somewhat different. I in the two arran ements;

has been cooled after the coatings 22 and 23 have been applied thereto.

The sheet 10 is kept constantly moving until the simulating strips have been made and severed from the sheet. The sinking of the projections 18-18 into the asphalt serves as means to assist the feed rollers 28 and 29 in pulling the sheet thru the machine.

The movement of the sheet is timed with respect to the knife 26, so that one revolution of the knifewill sever the sheet in proper lengths, in making the strips shown 2, or, in Fig. 4, they relative move- Tt will be main at the depressions'19 are fest of wurse, t

iormly separated so that the tabs will uni into shingle strips by cutting it be of uniform width and the shinglestrips of roper length.

avlng described my invention what I claim as new and desire to secure by Letters Patent is x The method of making shingle simulating strips which consists in providing an elongated sheet of roofing material comprising a base sheet having a coating of plastic asphalt of uniform thickness and a covering of finely divided mineral substance of contrasting color;. continuously moving the sheet, and while moving embedding a group narrow relatively long spaced, parallel straight areas of said mineral substance at separated regular intervals into the subjacent plastic coating until the latter'shows 0n the face of the sheet in simulation of separate shingles, then severing the sheet on a line in a plane with groups of areas, with the areas extending rom a common edge of the severed strips to the transverse mid-portion thereof, leaving substantially one-half of the strips, ex-

tending longitudinally thereof, unprovided with the depressed areas.

In testimony whereof I hereunto subscribed my name.
